Atec Bruel-Kjaer-2250-2270 - Manual

PRODUCT DATA
Type 2250 and Type 2270 are the innovative, 4th generation
hand-held analyzers from Brüel & Kjær. The analyzers’ easy,
safe and clever design philosophy is based on extensive
research. Type 2250 has been awarded several prizes for its
combination of excellent ergonomics and attractive design.
Both analyzers can host a number of applications, including
frequency analysis, logging (profiling) and signal recording, but in
addition, Type 2270 adds dual-channel capabilities such as
sound intensity/sound power measurements and dual-channel
building acoustics applications. Applilcations are available
separately at any time – or you can order a fully pre-configured
instrument from the factory.
The combination of application modules and innovative hardware
makes these instruments into dedicated solutions for performing
high-precision measurement tasks in environmental,
occupational and industrial application areas. As a result,
Brüel & Kjær delivers the functionality you need now, plus the
capability to add more functionality later – this is a very
secure investment.
